>LOL! Very good Alex! You are absolutely correct. Perhaps "Military Time" is dependant upon whose military, branch of the service, what your job was, and the context of the mission.
Here's a context-dependent definition, that I've found in an old railway timetable back home: "The midnight may be denoted as 0:00 or 24:00, depending on whether something begins or ends at that time. If a train arrives at midnight, it arrives at 24:00. If it starts at midnight, it starts at 0:00".
BTW, military time aside, we've been taught to speak in 24 hours since elementary school. Regular street talk was in 12-hour cycles, mostly for speed, except the hours which existed in both, like 5 to 12, so someone would say "tomorrow at nine", and get a reply "morning or evening?".
Abbreviations as "am" and "pm" were never even attempted, because they're both "pp" ("pre podne" - "pre noon" and "posle podne" - "post noon"). Also, nobody even mentioned using Latin abbreviations. It was simply "we go 24".
But anything that smelled even a tiniest bit official, we had to confess that the Earth really takes 24 hours to rotate - exact hours on the radio, any time table (incl. TV listings), publich watches (ever since they went digital) etc.
After all this, I came here and I can't find a microwave which is smart enough to know how many hours are there in a day.
Speaking of digital watches, a police squad (in Milosevic times) gets prepared for a raid, and commander says in the end:
"Let's set our watches. For those with hands, it's twelve to noon; for the digital, it's two nightsticks, upside down chair and a snowman".
